The purpose of this study is to examine the intensity of pruning on the leaf-area, the number of leaves and root-growth of Quercus myrsinaefolia Blume. We compared the root-growth, leaf-area and the number of leaves among three sections; severity pruning, slightly pruning, no pruning;. As a result, the slightly and severity pruning was considered to enlarge leaf-area. These were considered recovery reaction against the pruning. About the number of leaves, the slightly pruning was considered not to affect the total number of leaves, but to decrease the spring leaves, and contrarily the severity was considered to decrease the spring and summer leaves. These considered to affect top-growth in the severity pruning trees, in spite of the large leaves developed. About root-growth, the slightly pruning was considered not to affect the dry weight of roots, but many roots centered around the trunk, and contrarily the severity was considered to control the root-growth. The reason was that the balance was held between top-growth and root-growth.
